A service is the intangible equivalent of an economic good. Service provision is often an economic activity where the buyer does not generally, except by exclusive contract, obtain exclusive ownership of the thing purchased. The benefits of such a service, if priced, are held to be self-evident in the buyer's willingness to pay for it. Public services are those society as a whole pays for through taxes and other means.
By composing and orchestrating the appropriate level of resources, skill, ingenuity,and experience for effecting specific benefits for service consumers, service providers participate in an economy without the restrictions of carrying stock (inventory) or the need to concern themselves with bulky raw materials. On the other hand, their investment in expertise does require consistent service marketing and upgrading in the face of competition which has equally few physical restrictions. Many so-called services, however, require large physical structures and equipment, and consume large amounts of resources, such as transportation services and the military.
